8 Claims. (Cl. 292-11) This invention relates to a new and useful improvement in window hardware and deals particularly with devices for use in combination as fastening and hinging means for supporting and retaining storm windows or screens, and the like, in a window or door frame.

The desirable feasibility of more easily taking out and replacing storm windows with screens, or vice versa, is a problem constantly sought to be solved. The general practice as known to applicant is the provision of hooks serving as hinges, latches, and the ordinary looking hook and eye. In most instances, it is necessary to remove or replace the window or screen from the outside of the building. Otherwise, when removed from the inside, considerable reaching and manipulation is necessary to hang the window or screen tothe building frame.

Accordingly, it is an object of this new and useful improvement in window hardware to provide a structure entirely operable from within the building which permits placement of separable screen or window parts.

Another object is to provide a new and useful improvement in hardware for mounting storm windows and screens as two separate sashes in a single window, either of which sash is replaceable or may be left permanently in place as a permanent fixture.

A further feature is to provide a new and useful improvement in hardware cooperable between the window frame and the upper and lower sashes of screen and storm windows for holding the two sashes in place in the frameand also swingably supporting the lower sash.

Other objects and advantages will be apparent from the following description of the accompanying drawings herein:

The structure embodied in this disclosure is preferably used with replaceable screens and storm windows of a conventional type with the usual pair of vertically slideable sashes mounted in the guide grooves of a window in conventional fashion. These conventional guide grooves and window sashes are not shown in the drawings inasmuch as they are normally separated by a frame portion 10 from the insertable screens or storm window structures.

United States Paten 2,830,837 Patented Apr. 15, 1958 storm windows rest when slid into position in the win-.

dow frame.

In the new and useful improvement disclosed, the screens or storm windows are divided into upper and lower sashes, each of which may be replaced by its screen or storm window counterpart thereby providing an upper section which may be the storm window type and a lower section which may be a screen or vice versa as desired.

As illustrated in the drawing the upper sash 11 constitutes a window with vertical strips 12 and horizontal strips 13 forming the window frame. The lower sash 14 is a separate unit having the vertical portions 15 and horizontal portions 16 provided as the frame work for the screen structure.

On the upper portion 13 of the storm window 11 a bracket 17 cooperates with bracket 18 to hold the top of the window frame in close abutting relationship to the parting strip 10. The bracket 17 is fastened to the portion 13 by screw 19, and the upper portion of the bracket is curved outwardly and upwardly as shown in Fig. 7. The cooperating bracket 18 is fastened at its base with suitable screw means 20 to the parting strip 10. The bracket 18 carries a depending flange 21 which is curved outwardly to cooperate with the bracket 17, both in guiding the downwardly and outwardly flange 21 into the space provided by the upward and outwardly flared edge of bracket 17. This particular arrangement has been found to be to advantage, both as against parting strip 10 there is provided a holding plate 22 secured to the parting strip 10 by suitable screws 23. The holding plate 22 has an upper flange 24 provided with slot 25 positioned at right angles to the parting strip 10. The base of the holding plate 22 is also pro vided with a flange 26 at right angles to the base of plate 22 and in the flange 26 is an aperture 27 in align ment with the slot 25 provided in flange 24.

In order to secure the upper sash in a tight fitting relationship against the parting strip 10, each of the vertical sides 12 is provided with a holding bracket 28. The bracket 28 comprises a plate 29 which is provided at its lower end with an outwardly depending flange 30, and inwardly depending flange 31 which is inset into the sections 12 of sash 11. Secured over the top plate 29 by screw 32 is a catch or latch 33. The catch or latch 33 depends from holding screw 32 downwardly and outwardly to a pair of sharp bends 34 and 35 which lock under the prong 36 provided by slot 25 in flange 24.

By the catch or holding brackets 17 and 18 and the locking means 28 it will be recognized that a person' on the inside of a building can readily place the window sash into the outside edge portion 37 of a window frame, then slide the frame upwardly to cause holding bracket 21 to press against the holding bracket 17 inwardly of the Window frame. turned down into slot 25 to lock the sash 11 into the edge portion 37 and against the parting strip 10 of the window frame. The material forming the flange 24 may be sufficiently resilient to permit slight flexing of the flange during this operation. The slot 25 is U-shaped as indicated in Fig. 3 and the catch 33 as it rides over the edge of the slot holds the sash 11 into and against the parting strip 10. The depending outwardly turned flange of plate 29 rests upon flange 24 and keeps the sash 11 from dropping.

Then the catch or latch 33 In order to provide a hinged and flexible holding means for holding the sash 14 there is mounted in the aperture 27 of flange 26 a latch plate 38. The upper portion 39 of the latch plate 38 is a narrow section extending through aperture 27 and secured relatively permanently therein by spring member 40, washer 4i, and key 42. One end of the spring 40 rests against the top of flange 26 and the opposite end rests under tension against washer 41 to flexibly support the shoulders 43 of plate 38 against the bottom of flange 26. The lower portion 44 of plate 38 is provided with a cut out notch section to afford an indentation with platform 45 serving as a hinge point or rest for the flange 46 on bracket 47 which is secured by screws 48 to the lower sash M.

As indicated in the Figure 2 and Figure 5, the bracket 47 is secured to the upper vertical sections 15 of sash 14 and the angular flange 46 serves to hang and hinge the lower sash 14 in the window frame. The platform 45, as disclosed in Figure 2, is preferably sloped inwardly and downwardly and supports the flanges 46 at each side of the sash 14 in a relatively locked position.

As illustrated. more specifically in Figure 2 respective abutting of sash 11 with sash 14 at line 47 is in an offset relationship as shown. The break line 47 must necessarily be cut at cooperative angles for each of the sections 11 and 14 in order to prevent seepage of the elements. The spring 40 serves to lift the sash 14 against sash 11 and aids in preventing a loose fit at the juncture of the scperable sashes 11 and 14.

With the hinge point provided in the above manner described the lower sash 14 is provided with a handle 48 and a pair of flexible window brackets 49. The window brackets 49 are connected to the vertical parting strips on the inner side of the window frame and detachably connected to the sash 14. As illustrated, the flexible brackets 49 permit limited opening of the sash 14 and while they may be of conventional character with respect to being pivotally secured at 50 to part 10 with conventional arms 51 secured together in the middle by pivot 52. The end 53 is provided with a pin 54 adapted to be centered in an aperture in bracket 55 secured to the sash 14. The inner arm 51 is provided with a locking lever 56 mounted on bolt 57 which permits the lever to be rotated in order to fasten pin 54 to bracket 55 and hold the end 5.: of arm 51 in pivotal relationship to the pivotal bracket.

With the above description, it will be apparent as to the operation of the described hardware for attaching screens and storm windows into a window frame. It will also be apparent that the various bracket attachments as described can be interchangeably used upon the various sashes for interchangeably mounting corresponding upper and lower sash sections, if desired.

In accordance with the patent statutes, the principles of construction and operation of the divided window hardware have been described and while it has been endeavored to set forth the best embodiment thereof, it is desired to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of the present invention.
